Description
Technical field
The utility model is related to a kind of circuit connecting plate, more particularly to a kind of laser head circuit connecting plate.
Background technology
Laser head is the heart of CD-ROM drive, is also most accurate part, mainly responsible digital laser sound, the reading of video disc player data
Take work.LD（Laser Diode, laser diode）It is its main part, for TV, film and Karaoke（Mainly
The application of Karaoke）Two-sided video disc laser head on, laser head circuit connecting plate is the indispensable part of the product.
Traditional laser head circuit connecting plate structure is complex, is more expensive to manufacture.
Utility model content
The utility model is to overcome prior art not enough, there is provided a kind of to weld laser head electricity that is simple and arranging wire harness
Road connecting plate.
Specifically, the utility model provides a kind of laser head circuit connecting plate, including mainboard, the print being arranged on mainboard
The connecting portion and solder joint of brush circuit and connection printed circuit, the mainboard are provided with main body and the weld zone being connected with main part,
The solder joint is arranged at weld zone, it is characterised in that：Contraband shape groove is formed between the weld zone and main body, the solder joint lines up one
Row.
Further, the direction of the solder joint arrangement is perpendicular to two sides of Contraband shape groove.
Further, it is provided with guide part at the opening of the Contraband shape groove.
Further, the guide part is a kerf.
Laser head circuit connecting plate described in the utility model, by setting the arrangement mode of solder joint, simplifies Welder
Sequence, advantageously reduces cost, is provided with the arrangement that the Contraband shape groove of guidance part is then easy to wire harness.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model laser head circuit connecting plate.
Specific embodiment
Below in conjunction with accompanying drawing, laser head circuit connecting plate described in the utility model is illustrated without limitation, mesh
Be in order to the public more fully understands described technology contents.
With reference to as shown in figure 1, laser head circuit connecting plate described in the utility model include mainboard 1, be arranged on mainboard
Printed circuit（It is not shown）, connection printed circuit connecting portion 2 and solder joint 3.The mainboard 1 be provided with main body 11 and with main body 11
The weld zone 12 of part connection, the solder joint 3 is arranged at weld zone 12.
Contraband shape groove 4 is formed between the weld zone 12 and main body 11, Contraband shape groove 4 is used to arrange the wire harness of welding, it is to avoid line
Wrapping around.The solder joint 3 is arranged in a row, and its arragement direction is parallel to two sides 41,42 of Contraband shape groove 4.The Contraband shape groove 4
Guide part 43 is provided with opening, specifically, guide part is a kerf, wire harness can be arranged when wire harness is arranged.
Laser head circuit connecting plate described in the utility model, by setting the arrangement mode of solder joint, simplifies Welder
Sequence, advantageously reduces cost, and Contraband shape groove of the setting with guidance part is then easy to the arrangement to wire harness.
It should be understood that the above is not the limitation to the technical scheme, in fact, all with identical or approximate original
The improvement that is carried out to the technical scheme of reason, including each several part shape, size, the improvement of material used, and identity function
The replacement of element, all within the technical scheme that the utility model is claimed.
